Note:-
- The table is based on metric series of pipe dimensions given in ISO 161/1 (1978) in respect of pipe diameters.
- The wall thickness of pipe is based on a safe working stress of 8.6 MPa at 270 C. The working pressure gets reduced at sustained higher temperatures. Occasional rise in temperature, as in summer with concurrent corresponding reduction in temperature during nights has no deleterious effect on the working pressure of the pipes considering the total life of pipe.
